Meters with Pulse Output

Meters with Pulse Output

ThingsLogTM can measure consumption from meters with pulse output. In order to understand how does it work let’s first focus on what is a pulse. The Figure on the left illustrates a pulse output. Each pulse is characterized with an amplitude and a T_high and T_low. T_high is the duration of the pulse and T_low is anytime between two pulses.

Meters with Pulse Output

Depending of your meter one pulse might mean different things:
For water meters 1 pulse = 1 L, 10 L or 100 L, e.g one pulse is equal to 1, 10 or 100 liters of water
For gas flow meters 1 pulse = 0.01 m3, 0.1 m2 or 1 m3, e.g one pulse is equal to 1/100, 1/10 or 1 cubical meter of natural gas
For electricity energy typically you will get something like 1, 10, 100, 1000 W. E.g one pulse is equal to 1, 10, 100 or 1000 Watts.

Note: It is always better to get a meter with pulse output than a meter with integrated radio metering module. The integrated module typically could be read only by the vendor of the meter and the pulse output by anybody able to detect a pulse as the one above.

Note: It is always better to get a meter able to generate pulses on smaller quantities of water, gas or electricity. That will allow us to perform fine-grained monitoring and get your consumption right. ThingsLog offers various kinds of low-power data loggers able to meter any kind of meters with pulse outputs.
